It seems to me that tanks are now not working as intended.
They are so slow that infantry can walk faster. Moreover, if something stick out more than their tracks even on one cell they are getting stuck easily, making them generally just small buildings on tour, hardly of any use. And if you furthermore consider that travelling on strategic map is harder with them...
The speed listed in their characteristics is not achieved. Funnily, they move slightly faster while climbing up and down than on the planar surface.
Landships with legs instead of tracks are not getting stuck as easily, but are very slow too. They are moving strangely inclined to the front and sometimes almost fall on their knees.
I believe the moving speed of landships should be comparable with airships speed, especially as it is listed in their characteristics. 200kph landship is much, much slower than 60kph airship.
I assume the landships should always be positioned vertically, the only part adjusting to the surface should be their tracks? That way you should either not position anything outside of your tracks or some "loosiness" could be added to the land for objects to pass through corners of the it freely?
Maybe landships could gain more passability by rotating their frame on slopes.
Heavy landships should probably crumble the trees without slowing down much.
And it would be cool to be able to adjust the elevation of leg-landships over surface, but that is another topic (:
